FIG. 1 is a diagram showing the overall configuration of a power supply system 100 that supplies power to consumers in this embodiment. As shown in FIG. 1, the power supply system 100 in this embodiment includes a control device 101,

distributed power sources

102a, 102b, and 102c, a base power source 103, and

consumers

104a and 104b. The

consumers

104a and 104b refer to facilities such as homes, factories, and buildings, and are supplied with power from a power source configured in the power supply system 100. If the

consumers

104a and 104b are home facilities, they may have a home energy management system (HEMS) for managing electrical energy used in the home. Furthermore, if the

consumers

104a and 104b are commercial facilities, they may have a building energy management system (BEMS) for managing the electrical energy used within the facility. Although the number of consumers is illustrated as two in FIG. 1, the number is not limited to two. Hereinafter, the

consumers

104a and 104b will be collectively referred to as the consumers 104 unless they are distinguished from each other.

The

distributed power sources

102a, 102b, and 102c are operated when supplying power to the consumer 104. Distributed

power sources

102a, 102b, and 102c are movable (portable) power generation devices, unlike stationary power generation devices. Although three distributed power sources are illustrated in FIG. 1, the number is not limited to three. Hereinafter, the

distributed power sources

102a, 102b, and 102c will be collectively referred to as the distributed power source 102 unless otherwise distinguished. The distributed power source 102 includes devices using various power generation methods, such as a power generation device using a diesel engine, a power generation device using sunlight, a power generation device using wind power, and a power generation device using a fuel cell. Although the power supply system 100 includes a plurality of distributed power sources, not all of them are used to supply power to the consumers 104. Further, power is supplied to the consumer 104 via the power supply network 105, but since the distributed power source has a portable nature, it can be connected to/disconnected from the power supply network 105 as appropriate. That is, depending on the timing of power supply to the consumer 104, the operated distributed power source may change. The base power source 103 is a stationary power generation device with relatively low running cost. Like the distributed power source 102, the base power source 103 is used to supply power to the consumer 104, and may include devices of the various power generation methods described above.

In this embodiment, the area where the power supply system 100 is constructed is assumed to be an area that is not connected to the main power system from an electric utility company, such as a remote island. That is, the distributed power source 102 and the base power source 103 are used as power supply sources to the consumer 104. Note that in this embodiment, the base power supply 103 is not essential and may not be configured. That is, only the distributed power source 102 may be used as a power supply source to the consumer 104. Further, although the description will be made on the assumption that the device is not connected to a main power system from an electric power company such as a retail electricity company or a power transmission/distribution company, it may be configured to be connected to a main power system. At that time, the base power supply 103 may or may not be configured.

The operation control unit 304 controls the power storage operation, power generation operation, and connection/disconnection operation with the power supply network 105 of the distributed power source 102 . In this embodiment, the operation control unit 304 controls the above operations based on instructions from the control device 101. The device information monitoring unit 305 monitors the state of the distributed power source 102 based on signals from sensors (not shown) provided in each part of the distributed power source 102. The sensors include, for example, a sensor that detects the connection state of the distributed power source 102 to the power supply network 105 (for example, an open/closed state of a switch), and a sensor that detects the remaining amount of energy stored in the power storage unit 309.

The power supply unit 306 is a block for supplying power generated by the power generation unit 308 to the power supply network 105. The power generation unit 308 has a power generation configuration according to the power generation method of the distributed power source 102.

FIG. 4 is a diagram showing the flow of processing between the control device 101 and the distributed power source 102.

In S1, the operation planning unit 204 receives purpose information for power supply control from the administrator 401. Information reception may be performed, for example, by inputting on an interface screen displayed on the display unit, or by receiving information stored in another terminal via the communication network 106. good.

In S2, the load amount detection unit 206 periodically acquires the total power demand in the area managed by the control device 101 or the administrator 401, and transmits it to the system status monitoring unit 205. In S3, the system state monitoring unit 205 periodically acquires performance information and operation information from the distributed power source 102. Through the processes in S2 and S3, the system state monitoring unit 205 acquires the total power demand of the area it manages, and the performance information and operation information of each distributed power source 102 existing in the area.

FIG. 5A is a flowchart showing the process of acquiring the power demand amount executed by the load amount detection unit 206. The process in FIG. 5A is realized, for example, by the processor 201 reading out a program stored in the storage unit 203 into the memory 202 and executing it. Further, the process in FIG. 5A is repeatedly executed at predetermined time intervals.

In S<b>101 , the load amount detection unit 206 acquires the power demand amount from each consumer 104 . As described above, the consumer 104 has an electrical energy management system such as HEMS or BEMS, for example. In that case, the load amount detection unit 206 receives, for example, the total power of the consumer 104 in a predetermined period such as a month from an EMS (Energy Management System) control unit that controls the operation of power equipment installed in the consumer 104. Get the demand quantity. In S102, the load amount detection unit 206 adds up the amount of power demand acquired from each consumer 104 in the area managed by the control device 101. In S103, the load amount detection unit 206 stores the power demand obtained in S101 and the total power demand obtained in S102 in a database configured in the storage unit 203. After S103, the process in FIG. 5A ends.

FIG. 9A is a diagram showing an example of a database of power demand of each customer 104 stored in the storage unit 203. As shown in FIG. 9A, the power demand amount is stored in association with the identification information of each consumer 104. Also stored is the sum of the power demands of each customer 104 (total power demand) during the predetermined period. In other words, the total electricity demand in the area for a predetermined period is managed. The database in FIG. 9A is updated every time the process in FIG. 5A is executed.

FIG. 5B is a flowchart showing the process of acquiring performance information and operation information of the distributed power source 102, which is executed by the system status monitoring unit 205. The processing in FIG. 5B is realized, for example, by the processor 201 reading out a program stored in the storage unit 203 into the memory 202 and executing it. Further, the process in FIG. 5B is repeatedly executed at predetermined time intervals.

In S111, the system state monitoring unit 205 acquires performance information and operation information from each distributed power source 102. In S112, the system state monitoring unit 205 stores the performance information and operation information acquired in S111 in a database configured in the storage unit 203 in association with the distributed power source 102. After S112, the process in FIG. 5B ends.

FIG. 9B is a diagram showing an example of a database of performance information and operation information of each distributed power source 102 stored in the storage unit 203. The performance information is information indicating the performance of the distributed power source 102, and includes, for example, information regarding the power generation method and information on the load exerted on the surrounding environment when operating. The performance information includes, for example, information regarding the power generation method, power generation unit price, gas emission amount, and noise generation amount. The operating information is information indicating the operating state of the distributed power source 102, and includes, for example, the connection state (connection/disconnection) to the power supply network 105, operating time, power generation amount, and the amount of electricity stored in the power storage unit 309 (remaining energy amount). ), including operating status (normal, abnormal). The system state monitoring unit 205 may acquire the above information by acquiring specification information stored in advance in the storage unit 303 of the distributed power source 102. The device status monitoring unit 305 of the distributed power source 102 collects operating information as appropriate using sensors and the like provided in each unit. The system status monitoring unit 205 may acquire the operating information by transmitting an information acquisition request to the device information monitoring unit 305. The database in FIG. 9B is updated every time the process in FIG. 5B is executed.

Refer to FIG. 4 again. In S4, the system state monitoring unit 205 transmits the total power demand of the region obtained in S2 and S3, and the performance information and operation information of each distributed power source 102 to the operation planning unit 204. The system status monitoring unit 205 acquires each piece of information from the load amount detection unit 206 and the device status monitoring unit 305 at a predetermined timing. In other words, information is acquired so that there is no noticeable difference between the timing of acquiring the total power demand and the timing of acquiring performance information and operation information.

The operation planning unit 204 determines the area based on the total power demand acquired from the system status monitoring unit 205, the performance information and operation information of each distributed power source 102, and the purpose information of power supply control input in S1. The distributed power source 102 to be operated is selected from the distributed power sources 102 existing within the system. The operation planning unit 204 creates an operation plan for the selected distributed power source 102, and in S5 transmits instructions to start operation, generate electricity, store electricity, and stop operation to the operation control unit 304 based on the operation plan. When the operation control unit 304 receives an instruction regarding operation from the operation planning unit 204, the operation control unit 304 controls the operation start, power generation, power storage, and operation stop of the power conversion unit 307 according to the received instruction in S6. In S7, power is supplied from the power conversion unit 307 to the power supply network 105. On the other hand, in S8, if the device status monitoring unit 305 detects an abnormality such as an error within the distributed power source 102, it notifies the operation control unit 304. The operation control unit 304 transmits notification information indicating the occurrence of the abnormality to the operation planning unit 204.

In FIG. 4, the flow of processing is explained using step numbers, but the order is not limited to the time series of S1 to S8, and the order may be reversed between some processes. Further, the processes may be performed in parallel.

FIG. 6 is a flowchart showing the processing executed by the operation planning unit 204. The processing in FIG. 6 is realized, for example, by the processor 201 reading a program stored in the storage unit 203 into the memory 202 and executing it. The process in FIG. 6 is started, for example, when the administrator 401 instructs the start of operation. The instruction to start operation may be received via a user interface screen displayed on the display unit of the control device 101, for example.

In S201, the operation planning unit 204 acquires the purpose information of power supply control input from the administrator 401. This process corresponds to S1 in FIG. In S202, the operation planning unit 204 acquires the total power demand of the region from the system status monitoring unit 205. This process corresponds to S4 in FIG. Note that the operation planning unit 204 may obtain the power demand of each customer 104 and calculate the total power demand of the region. In S203, the operation planning unit 204 acquires the performance information and operating status of each distributed power source 102 from the system status monitoring unit 205. This process corresponds to S4 in FIG.

In S204, the operation planning unit 204 compares the total power demand of the region and the total power supply of each distributed power source existing in the region, and determines whether to start operation of the distributed power source 102. . Here, the regional total power demand is the total power demand acquired in S202. The operation planning unit 204 adds up the power generation amounts included in the operation information of each distributed power source 102 acquired in S203, and uses the summed value as the total power supply amount. In other words, in S204, the total power demand in the region is compared with the amount of power that can be supplied when all distributed power sources in the region are operated. In this embodiment, the comparison is performed as follows.

First, the operation planning unit 204 calculates the total power demand for determination by virtually increasing the total power demand. For example, the total power demand for determination is calculated using the following equation (1).

Total power demand for determination = total power demand acquired in S202 x α (1)
α in equation (1) is a coefficient for increasing the total power demand for determination, and a value of 1 or more, for example 1.2, is used. The coefficient is a predetermined value, and may be settable by the administrator 401.

Then, in S204, it is determined whether the following equation (2) is satisfied.

Total power demand for judgment ≦ Total power supply ... (2)
That is, in S204, it is determined whether the total power supply amount of each distributed power source 102 existing in the region exceeds the virtually increased total power demand for determination. Here, if the condition of formula (2) is satisfied, it means that the total power supply amount of each distributed power source 102 has a sufficient margin with respect to the total power demand obtained in S202, and the operation is started. It is determined that it is possible to do so. On the other hand, if the condition of equation (2) is not satisfied, it is assumed that the total power demand obtained in S202 and the total power supply are balanced, and if operation starts, some distributed power sources will be used. Since there is a risk of a power outage if the power supply network 102 is disconnected from the power supply network 105, it is determined that the operation should not be started.

If it is determined in S204 to start operation, the operation planning unit 204 creates an operation plan for each distributed power source 102 in S205. The operational plan will be discussed later. After S205, in S206, the operation planning unit 204 controls the operation of the distributed power source 102 to be operated, based on the timing planned in the operation plan created in S205. For example, the operation control starts the operation of the solar power generation type distributed power source 102 at 10:00 on November 20th, and stops the operation of the distributed power source 102 at 17:00 on November 20th. This is done according to the operating schedule.

On the other hand, if it is determined in S204 that the operation is not to be started, the operation planning unit 204 controls each distributed power source 102 to prohibit disconnection of each distributed power source 102 from the power supply network 105. Thereby, it is possible to prevent the risk of a power outage that may occur because the total power demand obtained in S202 and the total power supply obtained in S203 conflict with each other.

7 and 8 are flowcharts showing the process of S205 in FIG. 6. In S301, the operation planning unit 204 determines the purpose information of power supply control acquired in S201. For example, the determination in S301 may be made based on the objective item selected on the user interface screen displayed on the display unit of the control device 101. For example, a plurality of selection items may be displayed on the user interface screen along with a message such as "Please select the purpose of operating the distributed power source." In this embodiment, the following selection items can be selected by the administrator.

- Uninterrupted power outage - Ensuring remaining energy level - Economical efficiency - Environmental friendliness - Noise In S302, the operation planning unit 204 determines whether "uninterrupted power outage" has been selected as the objective item. "Uninterruptible" may be selected when the base power supply 103 is configured in the power supply system 100 of FIG. 1. If it is determined that "uninterrupted" has been selected, the process in FIG. 7 is ended and the process proceeds to S206 in FIG. 6. Then, in S206, the operation planning unit 204 controls the operation of each distributed power source 102 so that the power supply from the base power source 103 is stabilized. For example, when the power supply of the base power source 103 decreases, the operation planning unit 204 controls the distributed power source 102 that can compensate for the decreased power to select and start operating. Furthermore, when the power supply from the base power source 103 becomes excessive, the operation planning unit 204 selects a distributed power source 102 that can store the excess power and performs control to store the excess power. .

If it is determined in S302 that "uninterrupted" is not selected as the target item, the process advances to S306. In S306, the operation planning unit 204 determines whether "securing remaining energy" has been selected as the objective item. "Securing remaining energy" means always securing a predetermined amount of energy or more as surplus power, for example, in case of an emergency. If it is determined in S306 that "securing remaining energy" has been selected as the objective item, the process advances to S307.

In S307, the operation planning unit 204 calculates the daily power demand from the total power demand obtained in S202, and selects a distributed power source 102 that can supply power for the power demand. At this time, there may be multiple combinations of distributed power sources 102 selected.

For example, assume that the selected combination of distributed power sources 102 is as follows.

・Combination 1: Distributed power supply A+C+D
・Combination 2: Distributed power supply A+E
・Combination 3: Distributed power supply A+B+F+G
Combination 1 is an example of a combination of distributed power sources A, C, and D with a medium power generation amount. Combination 2 is an example of a combination of distributed power source A with a medium power generation amount and distributed power source E with a large power generation amount. Combination 3 is an example of a combination of distributed power source A with a medium power generation amount and distributed power sources B, F, and G with small power generation amounts. Here, it is assumed that the amount of electricity stored in the distributed power source E is greater than that of the distributed power sources A, B, C, D, F, and G. Further, it is assumed that the amount of electricity stored in the distributed power sources B, F, and G is smaller than that of the distributed power sources A, C, D, and E. The operation planning unit 204 determines the priority order of the combinations of the distributed power sources 102 based on the amount of power stored in the operation information. For example, in the case of the above example, the priority order is determined in descending order of the total amount of stored electricity, such as combination 2>combination 1>combination 3.
